A waterproof, dustproof, breathing bolt includes a bolt body having a hollow shank with a breathing chamber and a cap member fixedly located at the top side of the hollow shank and defining therein an air passage in communication with the breathing chamber and one or a number of openings in communication between the air passage and the surroundings, and a waterproof breathing member made out of a metal material by powder metallurgy and set in between the breathing chamber and the air passage and having micro pores therein of size larger than air molecules but smaller than water molecules. Thus, the waterproof breathing member allows discharge of hot air out of the apparatus in which the waterproof, dustproof, breathing bolt is installed, but prohibits external water from entering the apparatus.

Waterproof, dustproof, breathing bolt

Disclosed are a solar junction box and a wire connecting structure of the solar junction box. The solar junction box includes plural first conductive tongues separately and perpendicularly plugged onto a printed circuit board, plural solar panel conducting plates combined to the first conductive tongues, and each solar panel conducting plate including an extension plate connected to a solar panel and a U-shaped snap-in plate bent and extended from the extension plate, and each U-shaped snap-in plate being snapped onto each first conductive tongue, plural insulators sheathed on the solar panel conducting plates, a pair of second conductive tongues separately and flatly attached onto a side of the printed circuit board, and two conducting terminals electrically connected to the pair of second conductive tongues. With the installation of the wire connecting structure, the volume of the solar junction box can be reduced to provide a stable electrical connection.

Solar junction box and wire connecting structure thereof

A power module includes a metal housing formed of a metal case and a metal cover plate, a transformer module accommodated in the metal housing, including a base member having an iron core holder block suspending in a center opening thereof and two connection blocks disposed at two opposite sides thereof, metal conducting terminals arranged in two sets and respectively mounted in the connection blocks of the base member, a winding wound round the iron core holder block, two iron cores respectively attached to opposing top and bottom sides of the iron core holder block and two circuit boards respectively inserted into the two connection blocks of the base member and electrically coupled with two opposing connection terminals of the winding and respective vertical contact ends of the metal conducting terminals, and a thermo-conductive insulating glue filled in the metal housing to package the transformer module.
